I think my idea is kind of embedded among some comments here, but not too obvious so I will state it clearly here with my reasons. Here it is. My proposed brand name would be ...
One
Just One. sometimes can be abbreviated as O (in contrast to "X"!?). A possible longer version can still be "One by Leo".
Reasons being:
- It's one syllable word like Leo. Easy to pronounce (I considered Uno but it's two syllables).
- The meaning is straightforward and convey the Everything App message.
- The domain name could be a problem. But as I checked, leo.one is up for grabs for 10k. The domain looks cute as there is a lion inside: le(o.o)ne 😆
- Leo is lion and lion is king. There is only ONE king. The two concepts work well together.
- Some possible slogans: Make One Yourself! (which interestingly can be abbreviated as MOneY). Leo has become One. The Decentralized One - DONE.
Just my One cent.
